public abstract class InputStream extends InputStream
InputStream is the Java API for reading IDL types from CDR marshal streams. These methods are used by the ORB to unmarshal IDL types as well as to extract IDL types out of Anys. The_array
versions of the methods can be directly used to read sequences and arrays of IDL types.- Since:
- JDK1.2

read
public int read() throws IOException
Description copied from class:InputStream
Reads the next byte of data from the input stream. The value byte is returned as anint
in the range0
to255
. If no byte is available because the end of the stream has been reached, the value-1
is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.A subclass must provide an implementation of this method.
- Specified by:
read
in classInputStream
- Returns:
- the next byte of data, or
-1
if the end of the stream is reached. - Throws:
IOException
- if an I/O error occurs.- See Also:

read_fixed
public BigDecimal read_fixed()
Reads a BigDecimal number.- Returns:
- a java.math.BigDecimal number
-
read_Context
public Context read_Context()
Reads a CORBA context from the stream.- Returns:
- a CORBA context
- See Also:
portable
package comments for unimplemented features
-
read_Object
public Object read_Object(Class clz)
Unmarshals an object and returns a CORBA Object, which is an instance of the class passed as its argument. This class is the stub class of the expected type.- Parameters:
clz
- The Class object for the stub class which corresponds to the type that is statistically expected, or the Class object for the RMI/IDL interface type that is statistically expected.- Returns:
